Hi Guys,
I just need a bit of advice please for anyone who has a freesync monitor.
Ive recently been getting what you can call ‘microstutters’ and slight screen tearing but this can happen anywhere and I’m fairly certain it’s how my monitor is receiving information from my nvidia graphics card as it’s the same when I’m in busy photogrammetry areas and 33,000 feet over the desert.
I have been trying to mess around tuning it with the control panel and my freesync monitor as I’m sure this can sort it, I do get a better performance by doing this but i’m not entirely sure what I’m doing 
I’ve tried enabling gsync in the control panel but is freesync and gsync two entirely different things?, should freesync automatically kick in when I enable it on my screen or is there something else I’m missing?
Sorry if these questions come across as stupid but I’m new at all this and I’m currently trying to earn it all 
Anyone with a simiar setup that has got the best out of your freesync monitor, I would love to hear from you
Cheers guys,
Ste.

Google G Sync vs. Freesync, for a quick bit of info on the two. G Sync is employed in Nvidia cards, while Freesync applies to AMD cards…
Perfect, thanks a lot for this.
So I’m guessing (with the information I’ve been reading) I could turn off my vsync and FPS limiter as my monitor (what is now showing ‘Freesync Enabled’ so I must have connected it correctly!) seems to have connected to it properly?, it does seem to advise to switch this off if your monitor is over the FPS that you will receive (60Mhz)
I’m definitely getting under 60fps most of the time 
What monitor and what graphics card are you using? I’m using a Gigabyte RTX2060 Super with an approved Gigabyte 32" monitor. I have G sync/G sync compatible enabled and tested, the monitor is Freesync, the Nvidia card is G Sync. Seems fine, tests OK. Definitely runs less than 60 FPS. Microstutters seem to happen occasionally, but not enough to be a major problem with my older graphics card. You can shut off sync and try it, won’t hurt anything, but I’d be surprised if any major changes were noted.
You have to check if your monitor is supported by nvidia for freesync, if not it might not work at all. Turn on your monitor fps in the osd of your monitor to see if its even syncing.

Cheers for your reply guys!
I’m using a 2080 super graphics card, Intel 7 I9700k processor and 32 gig of RAM!, I have a 32 inch monitor that is showing ‘Freesync Enabled when I go onto the monitor OSD so I assume it’s working, however it’s still stuttering big not as bad!
On Nvidia Control panel, I’ve got a max of 30FPS with vsync also enabled, I keep thinking I’m missing something that will suddenly change the game and start it running smoothly again

Yup, some of the unsupported monitors will work just fine, others, not so much.
I think you’re doing not too bad, considering all the posts regarding stutters and 3 to 5 FPS.
Oh yeah, I agree with you that the problem is minimal to some of the guys who are suffering with there performance problems!
I flew into Paris about an hour ago right over the centre and got amazing views and performance was rather good, the main sticking point is when I’m up in the air at 34,000 feet in the 747, I seem to be getting very annoying ‘micro stutters’ when my GPU, CPU and memory are going great!, there should be none of them when the system isn’t under any strain but it spoils the whole realism of the flight when I get them, it must be every 5 seconds are so.
I was curious if anyone else has these and if we can just put them down to the game itself and await a patch from them, or I could try to optimise my system to make these go away
I have two computers that I use for Flight Simulator. Thanks to FreeSync I managed to reduce stuttering noticeably on both. Tips follow.
Make sure that the monitor has FreeSync/GSync enabled. I had to use an on-screen menu on one of my monitors to get that done.
I set a high refresh rate in Windows instead of the default value of 60 FPS. This may not be necessary for FreeSync to work properly, but I haven’t tested FreeSync games with the desktop running at default 60 FPS.
Disable VSync on Flight Simulator. With VSync enabled I get stuttering unless I drop the refresh rate to 30 FPS on the Flight Simulator settings. It seems that VSync prevents FreeSync from doing its adaptive frame rate shenanigans. It may be different for Nvidia users.
To avoid over-stressing my GPU, I use a feature on AMD software called Radeon Chill, which allows me to cap FPS to 60 or less while VSync remains disabled in-game. I rather have a quiet graphics card and a smooth constant frame rate than very high refresh rates and lots of stuttering in Flight Simulator. I expect a similar feature to be available for Nvidia users.
Your CPU is essential to avoid stuttering. There is an FPS monitor available on Flight Simulator when developer mode is enabled. If it tells you that the game is limited by the main thread, then CPU is your bottleneck. Try running the simulator in medium settings, or cap the frame rate at a lower value.
I increased the rolling cache size in Flight Simulator, although I am not sure that it helps.

Thanks for your tips, much appreciated!
What I’ve done is set my vsync to half refresh rate (my monitor is 60mh) , set my limit to 60fps in the nvidia control panel and that has seemed to do the trick!
I’ve read a few online instructions on how the graphics card to monitor works and the best tip I’ve seen is try to keep your FPS to a division of the MH of your monitor, so I changed this and I’ve found my system has responded to this by giving me a smoother picture.
Ok, the stuttering is still slightly there when I’m coming into a city with photogrammetry but on the whole the smoothness is so much better!
Now I’ve made it a lot smoother I’ve promised myself I’m not going to mess with the settings anymore in case it reverts back to a stutter fest 
, at least now until the next sim update is out, I’m happy 
That works too, but if you have a monitor that has FreeSync or GSync capabilities, you are leaving a smooth experience on the table.
If Flight Simulator could generate 60 frames per second (FPS) consistently, and your monitor is set to refresh at 60 Hz (cycles per second), you would be OK. VSync makes sure that you get each frame sent to the monitor at a the right time, and you won’t get screen tearing, which happens when a new frame is sent to the monitor the current one hasn’t finished displaying.
But Flight Simulator is usually incapable of drawing 60 frames per second, so with VSync enabled at 60 FPS, you will get stuttering, which happens when frames are further apart than the refresh rate of the monitor, at a rate that does not divide it exactly. You may be better off in case setting Flight Simulator to 30 or even 20 FPS (both divide 60 exactly). You’ll see what I mean if you try it. No stutters, but it will look like stop-animation.
With FreeSync or GSync enabled, the monitor will synchronize with the game. If Flight Simulator is drawing 45 frames per second, the monitor will refresh at 45 Hz (some caveats apply). All frames will be displayed as they arrive, and the experience will be much more fluid.
Yeah, I see what your saying, and this makes me think my monitor isn’t working correctly when trying to connect via. Freesync because I’m getting bad stutters by trying what you say!, I’m probably getting 30-40FPS normally but the stutters are there however by doing the half refresh rate, I’m getting it so smooth and I suppose it’s what you can put up with what counts to me as I can fly with my sim being like this as the smoothness is great!
Have you got a similar setup to me?, if you let me know what you have as your control panel setup I could give that a try and see if my system performs better, however I’m a happy chappy with how my system is at the moment
Write down the model of your monitor and the model of your graphics card. It is likely that your monitor is like my mine and doesn’t have FreeSync active by default.
Hopefully that works!, it’s a 24inch LG monitor, it does say it’s Freesync compatible!, my graphics card is Nvidia 2080super.
I tried changing absolutely everything and had really bad stutters with all that I’ve tried!, it got to the point I was thinking of quitting the game because I was spending more time messing around with the control panel and options than playing the game but since finally cracking it, I’ve spent a good 4/5 hours flying, stutter free this weekend
This seems to be the official website for your monitor. On the right side there is a user manual link that points to a PDF file. If you open it and look for FreeSync, you’ll find that there is a setting to activate that in the monitor menu under Picture > Game Adjust. You have to set it to Extended or Basic to get FreeSync activated. The manual should show you what buttons you should press on the monitor.
Once you have that enabled, it remains to activate GSync on the Nvidia software. For that this article should give you the instructions that you need to follow.
Then do not forget to disable VSync in the Flight Simulator graphics settings to get the actual benefits.
If you manage to do it, respond with a thumbs up to let everyone else know that it worked.
I’ve already tried this but it was still stuttering!, that’s the most frustrating thing about it all, according to everything I was reading online, it should have been working fine but there still was major stutters!
It does make me think that there’s something under laying in the game that’s causing this issue, as my current settings appear to be the smoothest I can get!
I really appreciate your help though, it’s much appreciated , I may be tempted to change my settings again when the SU4 comes out next month when they have promised a performance update but until then, I’ll stick with my current settings as it’s the best my system is performing for a while
What is your CPU? You are likely to be CPU-bound.
My CPU is I7 9700k, could this have a big part to play in it then?
Look at this comparison here. I have both of the AMD processors there. Both of them stutter a little bit. The machine where I have the Ryzen 9 3900X runs with High graphics on a Radeon RX 5700 XT. The machine with the Ryzen 9 5900 has a Radeon RX 6800 XT and runs Ultra graphics.
I’d say that Flight Simulator can benefit from a faster CPU. It is complicated because even while it uses all CPU cores available, it still seems to rely on single-core performance for some tasks that cannot benefit from concurrency.
Your CPU has a low CPU mark compared with mine, but both its single-core performance and its core count seem to be high enough so that you can at least get up to 55 FPS with minimal stuttering outside the largest cities (New York is pretty heavy and your performance can drop as low as 30 FPS with annoying stuttering depending on your graphics settings).
I found that there is no way to avoid a little stuttering, even with a powerful system running medium/low settings. Flight Simulator probably needs a bit more optimisation on the CPU side of things. Or maybe Asobo ran out performance tricks, which is why they can make this look so good and run almost smoothly.
Some monitors have a way to show the refresh rate for diagnostic purposes. When Free/GSync is enabled the refresh rate will be all over the place. If it is not working the refresh rate will look stable at 60 Hz, usually. Try to find that in your monitor and activate it. That should at least give you assurance as to whether GSync is actually being used.
